If anyone has any objections, please let me know. ------------------ From: Pavel Begunkov commit cf73d9970ea4f8cace5d8f02d2565a2723003112 upstream. __kernel_rwf_t is defined as int, the actual size of which is implementation defined. It won't go well if some compiler / archs ever defines it as i64, so replace it with __u32, hoping that there is no one using i16 for it.
